[xsl] variables, grouping, and result-documents

[Terry Ofner <tofner@xxxxxxxxxxx>]

I am having trouble naming result documents. Here is a style sheet  
that included two-level grouping and a result-document statement.

<xsl:stylesheet version="2.0"
     xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
     xmlns:fo="http://www.w3.org/1999/XSL/Format";>
<xsl:output method="xml" indent="no"/>

<!--State Standards file-->
<xsl:variable name="StateFile" select="document('stateCodes.xml')" />
<xsl:key name="standard" match="state" use="@abbr" />

<!--Lesson Name file-->
<xsl:variable name="lessonFile" select="document('Grade4Skills.tab')" />
<xsl:key name="lessonName_by_num" match="skill" use="@num" />


  <!--start grouping by states and naming result-documents-->

  <xsl:template match="/">
    <xsl:for-each-group select="/Root/Story/State_Standard" group- 
by="@state">
     <xsl:variable name="stateName" select="current-group()/@state"/>
        <xsl:result-document href="{$stateName}.fo">

<!--Define FO page layouts and Place State Standard at top of table-->
<!--fo:master page formatting cut out:-->

<fo:static-content flow-name="headerRest">
        <fo:block text-align="end"
          font-size="10pt"
          font-family="serif"
          line-height="14pt" >
          Reading Express Level D / <xsl:variable name="LocalState"  
select="$stateName" />
          <xsl:for-each select="$StateFile">
            <xsl:value-of select="key('standard', $LocalState)" />
          </xsl:for-each> Correlation - p. <fo:page-number/>
        </fo:block>
      </fo:static-content>

      <fo:flow flow-name="xsl-region-body">
<fo:block font-size="16pt"
          font-family="sans-serif"
          font-weight="bold"
          line-height="24pt"
          space-after.optimum="15pt"
          background-color="gray"
          color="white"
          text-align="center">
 <xsl:variable name="LocalState" select="$stateName" />
<xsl:for-each select="$StateFile">
<xsl:value-of select="key('standard', $LocalState)" />
</xsl:for-each>
        </fo:block>
  <fo:block font-size="11pt"
    font-family="serif"
    line-height="24pt"
    space-after.optimum="15pt"
    background-color="white"
    color="black"
    text-align="left">
    <xsl:variable name="LocalState" select="$stateName" />
    This chart correlates the <xsl:for-each  
select="$StateFile"><xsl:value-of select="key('standard',  
$LocalState)" /></xsl:for-each> to the lessons of Reading Express,  
Level D.
  </fo:block>


<fo:table-body>
       <xsl:for-each-group select="current-group()/SS" group-by=".">
            <xsl:sort select="."/>
         <fo:table-row border-color="black" border-width="0.5pt"  
border-style="solid" keep-together.within-page="always">

           <fo:table-cell padding="4pt" keep-together.within- 
page="always">
          <fo:block text-align="left" font-size="11pt" font- 
family="serif" text-indent="-24pt" start-indent="24pt">
              <xsl:copy-of select="node()"/>
          </fo:block>
        </fo:table-cell>
              <xsl:variable name="skillNumber" select="current-group 
()/../@skill"/>
                  <xsl:for-each select="$lessonFile">
                    <fo:table-cell padding="4pt" keep- 
together.within-page="always">
            <fo:block text-align="left" font-size="11pt" font- 
family="serif">
              <xsl:copy-of select="key('lessonName_by_num',  
$skillNumber)/child::node()" />
          </fo:block>
         </fo:table-cell>
         </xsl:for-each>
      </fo:table-row>
             </xsl:for-each-group>
</fo:table-body>
  </fo:table>

  </fo:flow>
    </fo:page-sequence>
  </fo:root>
      </xsl:result-document>
    </xsl:for-each-group>
  </xsl:template>
</xsl:stylesheet>

The source xml contains multiple standards each for all 50 states and  
DC.

<?xml version="1.0"?>
<Root>
    <Story>
        <State_Standard skill="01" state="AZ">
            <State>Arizona Standards</State>
            <SS>1.4.1 Use knowledge of root words and affixes to  
determine the meaning of unknown
                words.</SS>
        </State_Standard>
    </Story>
      <State_Standard skill="29" state="CA">
            <State>California Standards</State>
            <SS>2.1 Identify structural patterns found in  
informational text to strengthen
                comprehension.</SS>
        </State_Standard>
    </Story>
</Root>

The contents of the resulting documents look great. It is the  
resulting file names that are loopy. Here are the names of two of my  
resulting files:

FL FL FL FL FL FL FL FL FL FL FL FL FL FL FL FL FL FL FL FL FL FL FL  
FL FL FL FL FL FL FL FL FL FL FL FL FL FL FL FL FL FL FL FL FL FL FL  
FL FL FL FL FL FL FL FL FL FL FL FL FL FL FL FL.fo

and

CA CA CA CA CA CA CA CA CA CA CA CA CA CA CA CA CA CA CA CA CA CA CA  
CA CA CA CA CA CA CA CA CA CA CA CA CA CA CA CA CA CA CA CA CA CA CA  
CA CA CA CA CA CA CA CA CA CA CA CA CA CA CA CA.fo

It seems that I have this variable line in the wrong place:

<xsl:variable name="stateName" select="current-group()/@state"/>

Am I trying to do too much inside this one template?
Do I need two templates?

Thanks in advance,
